Sulbactam/ampicillin versus metronidazole/gentamicin in the treatment of post-cesarean section endometritis.

Sixty-seven patients diagnosed with post-cesarean-section endometritis were studied in a prospective comparative randomized trial of sulbactam/ampicillin, a new beta-lactamase inhibitor drug combination, versus treatment with metronidazole/gentamicin. The success rate was 91% for each antibiotic regimen. Mycoplasma spp. or Ureaplasma spp. were isolated from all treatment failures. Endometrial cultures revealed 2.3 aerobes as well as anaerobes per patient, with Enterococcus faecalis, Bacteroides bivius, and Escherichia coli the most frequently reported bacterial isolates in 64, 40, and 28% of all patients, respectively. Positive blood cultures were noted in 11 (15%) patients with Mycoplasma sp. the most commonly found isolate (45.5%). Sulbactam/ampicillin appears to be safe and equally effective as a metronidazole/aminoglycoside drug regimen in the treatment of postpartum endometritis.
